When the Linksys DMA2100 first starting shipping I said that it would decode DivX (in addition to the listed Xvid support), just to have to put my foot in my mouth because no one could get it work.  As I’ve said time and time again, DivX and Xvid are just MPEG-4 ASP.  DivX is a brand, Xvid is a brand.  The video still complies with a standard and can thus be decoded by any MPEG-4 ASP decoder.

Sadly, Linksys screwed this up by blocking playback of DivX files.  They are doing this blocking certain FourCC’s (an identifier) in AVI files.  AVI’s that report a FourCC of xvid work fine.  AVI’s that report a FourCC of DIVX or DX50 don’t work.

The fix was brought up at The Green Button and just involves changing that FourCC.  This process is very simple using a program like AVI FourCC Changer.  Open your AVI files and just change the FourCC to “xvid.”  Simple as that, the files will now playback just fine.

Thanks ilyo and everyone with Linksys Extenders!
